Why the smell from the sink

To understand how to get rid of the smell from the sink, you need to start "diagnose" the reason for its occurrence. Plumbing equipment - sinks, toilets and showers - are associated with a common riser sewer via water seal (So-called knee) or corrugated pipe of the siphon. water gathered there forms a plug which prevents ingress of gases from sewage pipe in apartment.

The most common causes of bad smell from the sink in the kitchen:

• the lack of water in the "knee";
• clogging of drain tube or siphon;
• deformation and wear of the corrugated portion of the siphon;
• seal failure pipes;
• Improper installation of sewer system.

Lack of water in the siphon

If the sink for a long time not to use (for example, when the owners leave the apartment in a long vacation or business trip) water in the trap can evaporateAnd the smell of sewage penetrate into the apartment through the drain hole. It's pretty simple and easy to fix problems: flush enough and unpleasant "smell" will disappear immediately after airing.

clogged drain

Clogged sink - it's trouble, which at times faced by any, even the most accurate hostess. Leftover food, tea leaves, eggshell, oil and grease, fall into the drain when washing dishes and accumulate in the "knee" (especially this sin siphon bottle type). Food waste They begin to decompose quite quickly, especially during the hottest time of the year, besides the organic waste It is an excellent breeding ground for bacteria, which also contributes to the appearance of an unpleasant smell.

Folk remedies for odor

If the drain is not clogged, "tight", and a bad smell from the sink is still there, then it could be because fatty plaque on the walls pipes. Get rid of this problem as possible, using the simplest means, which are in each kitchen.

usual baking soda copes with the splitting of fat. 50-80 g (2-3 tablespoons) soda to dissolve in one liter of hot water and pour the resulting mixture into the drain hole. After a few minutes a power wash pipe of hot water. If necessary, repeat the procedure several times. The process will be more efficient if the fill soda drain and fill it with liquid acidic: lemon juice or vinegar 9%. The resulting vigorous reaction can easily cope with the cleaning pipe from both organic and calcareous deposits.

Alternatively, the ash may be mixed in equal proportions with granules of citric acid, Pour the mixture into the sink and pour boiling water to two liters.

The use of chemical reagents

To cleanse fatty plaque can use household chemicalsContaining bleach, an alkali or an acid. For example, take a conventional laundry detergent, bleach or wash solution to grills and ovens.

If the blockage is so strong that it prevents the penetration of water, it is best to resort to professional tools designed Clean-Out for sewerage.

First we need to empty the water from the sink, pour the product into granules sink and pour the quantity of boiling water, is directed on the package (better boil water in advance). After that, the recommended wait time instruction, and then rinse sewers within a few minutes power shower.

Important! Reagents can cause chemical burns of the skin, mucous membranes of the eyes or respiratory tract, so you need to use them with extreme caution, avoiding inhalation of vapors and contact with hands and face.

Mechanical methods of removing blockages

Alas, chemistry handle is not everything. Small blockage can be punched by a conventional plungerWhich is in every house. To begin to plug the drain hole in the shell and collect water, preferably hot. Then firmly press the bulb into the drain and vent by pressing the plunger. The pressure drop created within the tube, stopper break may not be the first time.

sanitary cable - a metal spiral in length from one to a few meters, which is used to remove the debris, clogging drain. They are sold in any hardware store, but in an emergency, you can make your own rope of tough, good to keep the shape of the wire. Cable neatly put into the sink until he utknetsya an obstacle. Then you try to push the plug or pick up trash, rotating spiral. Carefully remove the cable and check whether the water flows well.

Unfortunately, the above purification methods is not possible when used as a siphon bellows or as it is also called "flute" - a popular low-end solution for the sewage system. Pressure drops generated plunger and sanitary cable can break the pipe wall.

dismantling drain

If the chemical and mechanical methods have not led to a positive result, it remains a last resort: dismantle the trap and clean out debris and foreign objects manually. This can be done only for those who have experience of similar work - incorrect assembly will result in much more dire consequences such as leakage and breach of sealing joints.

Leak or crack in the pipes

The emergence of "bad" odors in the apartment can also be caused by depressurization of the sewer system. Find invisible leaks can be spending on pipes and joints with a paper towel.

Eliminate the problem of need depending on the size and nature of depressurization: replace the pipe or connecting element, change seals and treat joints with silicone sealant.

Poor quality system installation

Mistakes made when installing the sink, it can cause an unpleasant sewage smell in the kitchen.

The most common of them:

• Mounting tubes were used with a diameter less than the recommended amount, which leads to the disruption of the water trap;
• siphon mounted wrong angle bend, which prevents the formation of water plugs;
• siphon corrugated tube can lose shape over time;
• Siphon has manufacturing defect or was damaged during installation;
• functioning of the common riser was broken while repairs neighbors above or below.

In all these cases it is better to address an experienced plumberWho will diagnose and eliminate the cause of the smell of sewage.

Prevention of the formation of odors from the sink

In conclusion, a few preventive measures that will prevent the appearance of unwanted odors in the kitchen:

1. When installing sewer is better to choose the ideal smooth inside pipe. Rough or ribbed inner surface promotes the formation of a food or lime, which, in turn, lead to the formation of blockages.
2. regular preventive cleaning and disinfection of sewer walls using household chemicals will help prevent the occurrence of blockages and odors from the sink.
3. Radical solution that will get rid of clogged sink once and for all: installation of waste shredder. This device allows you to split any, even a fairly solid waste into a fine dust, which is free to wash off the drain.
4. Before leaving in the long term should pour a little oil in a stock hole: it forms a film, which will prevent the evaporation of water. Returning home, will be enough to wash out the drain system in the usual detergent.
